The synthetic methods
Method of chlorosulfonic acid with chlorobenzene and chlorosulfonic acid reaction was 4 - chlorobenzene sulfonyl chloride, then condensation with chlorobenzene in the presence of aluminium trichloride, the refined for a quick finished products.
Sulfuric acid method with industrial sulfuric acid, chlorobenzene as raw material, using the method of intermittent or continuous method and cost of product, reaction was conducted in the presence of an excess of chlorobenzene.
Product use
